The formula for specific gravity is:
where 
is the density of the substance and 
is the density of water.
The density of water, = 
Substituting the values in above formula we get,
The formula of density is:
The density of mercury is 
The mass of mercury is 
Substituting the values in density formula:
Answer:
. BCG growth-market share matrix
Explanation:
The growth-share matrix is a business portfolio that main aim is to divide the different businesses of a company according to priority. it includes the different criteria on which different businesses can be prioritized. it includes four different quadrants that show its own profitability criteria. the four-quadrant are question marks, stars, pets, cash cows.
Answer:
<u>253.33 mmHg</u>
Explanation:
According to Charles' Law,
P₁ / T₁ = P₂ / T₂
P₁T₂ = P₂T₁
P₂ = P₁T₂ / T₁
= 760 x 40 / 30
= 760 x 4/3
= 1013.33 mmHg
Change in Pressure
= 1013.33 - 760
= <u>253.33 mmHg</u>
Answer:
1. 2.04 W/m²
2. 1.63°C
Explanation:
The radiative force that the Earth receives comes from the Sun. When the Sun rays come to the surface, some of them are absorbed and then it is reflected in the space. The greenhouse gases (like CO2) blocks some of these rays, and then the surface stays warm. The excessive amount of these gases makes the surface warmer, which unbalance the climate on Earth.
1. The variation of the radiative forcing can be calculated based on the concentration of the CO2 by the equation:
ΔF = 5.35*ln(C/C0)
Where C is the final concentration, and C0 is the initial concentration.
ΔF = 5.35*ln(410/280)
ΔF = 2.04 W/m²
2. The temperature change in the Earth's surface caused by the variation of the radiative forcing can be calculated by:
ΔT = 0.8*ΔF
ΔT = 0.8*2.04
ΔT = 1.63 K = 1.63°C
Spectroscopy because it talks about the study of spectrum of light.
